import { Deno } from "https://deno.land/x/deno@v2.0.4/cli/tsc/dts/lib.deno.ns.d.ts";
const { consoleSize } = Deno;
Gets the size of the console as columns/rows.
const { columns, rows } = Deno.consoleSize();
This returns the size of the console window as reported by the operating system. It's not a reflection of how many characters will fit within the console window, but can be used as part of that calculation.
